Inertia. Newton's First Law of Motion: "A body at rest tends to stay at rest, while a body in motion tends to stay in motion."
Objects stay in place when the forces acting on them are balanced. When gravitational force pulling an object down is equal to the opposing forces (such as friction or tension) preventing the object from moving, the object will stay in place. This balanced condition is known as equilibrium.
An object that appears to stay in place is likely stationary relative to the observer. This can occur when an object is not moving in relation to the observer's frame of reference, creating the perception that it is fixed in place.

That is equivalent to saying that: * The object is moving, or * The object doesn't stay all the time in the same place.
you put a bed like object in a place that will stay dry, some familiar objects, and some food and water.
That means that the object is moving - that it doesn't stay in the same place all the time.

For an object to stay in place - unmoving - two conditions must be fulfilled:* The sum of all forces on the object must be zero. * The sum of all torques on the object must be zero. Usually the forces that tend to keep an object in place (despite forces such as gravity or wind) are anything holding it fast in place - including friction.
This is called a reference point.
Resistance keeps an object in place. This resistance can come from friction, which works against motion, or from an obstacle of some kind that is prohibiting movement. In terms of vertical motion, gravity holds all objects to the earth and keeps them firmly planted on the ground.An object at rest tends to stay at rest unless acted on by a forceAn object in place will stay in place unless acted upon by a force. So if you kick a box in place on the floor it will move. There is always a force of gravity pulling it down, bu the force of gravity is resisted by the floor which keeps it in place (equilibrium - no net force). If you cut around it and make a hole in the floor it will move straight down.
